N-Arachidonoyl dopamine (NADA) and N-Arachidonoyl serine (ARA-S), among various arachidonoyl amino acids, have been extracted from bovine brain, while a novel series of fatty acyl amides of taurine were unearthed in rat brain through mass spectral lipidomic analysis, indicating the discovery of a new class of compounds also located in the kidney. These compounds are known to activate members of the transient receptor potential (TRP) family of calcium channels. Notably, N-Stearoyl taurine emerges as a significant amino-acyl endocannabinoid identified in rat brain lipidomics profiling.
